The influence of plasma screening on the energy levels and oscillator strength for ions in a high-temporary plasma is investigated by using the Debye-model. The 2s2—2s1/2,2p1/21 and 2s2—2s1/2,2p3/21 transitions of 11 beryllium-like ions from MnXXII to BrXXXII are calculated by including the effect of plasma-screening. The results show that the effect of plasma-screening increases the 2s2—2s1/2,2p1/21 transition energy of beryllium-like ions, which leads to a blue-shift; it also shows that the blue-shift becomes more and more obvious as the plasma-screening increases. The overall trend for the oscillator strength of the 2s2—2s1/2,2p3/21 transition is similar to that of the transition energy.
